QS1 Installation/User Manual
8.Technical Data
1 . Be sure to verify the voltage and current specifications of your PV module.
It should match with those of the Microinverter. Please refer to the datasheet
or usermanual which can be download from APsystems website
global.APsystems.com.
②. You must match the DC operating voltage range of the PV module with the
allowable input voltage range of the APsystems Microinverter.
③. The maximum open circuit voltage of the PV module must not exceed the
specified maximum input voltage of the APsystems
Grid Support Details
The QS1 is a grid support interactive inverter. This type of inverter is also known as a Grid
Support Utility Interactive Inverter . The QS1 also comply with California Rule 21. The grid
support function is controlled by ECU .
Simultaneous use of Fixed Power Factor and Volt/VAr is not supported.
